EV SYSTEM MAINTENANCE
• Malfunction in opening/closing the charge port caps and looseness when closed and locked.
• Check that the normal charge port terminals are not bent.
• Check that the contact prevention cap is not missing.
NOTE:
If it is missing, it is extremely difficult to engage the charge
connector.
• Check that there is no snow or ice on the normal charge port
top side .
NOTE:
If snow or ice reaches the charge connector lock, charging
does not start.
Handling of charge port
Cleaning of charge port
If the charge port becomes dirty, clean the port with an air blow gun.
Handling of damaged cap
Perform the following procedure if the cap becomes damaged:
• Replace charge port cap if the charge port cap becomes damaged
• Replace charge port if the packing of quick charge port becomes cracked.
• Replace charge port if the terminal of quick charge port or normal charge port becomes damaged.
Cleaning of the inside of rubber cap
If air does not exit through the rubber cap hole, remove the rubber cap from the port and clean the inside so
that air exits through the rubber cap hole.

REDUCTION GEAR OIL
REDUCTION GEAR OIL : Inspection
INFOID:0000000010121530
OIL LEAKAGE
Check reduction gear surrounding area (oil seal, drain plug, and filler plug etc.) for oil leakage.
OIL LEVEL
• Remove filler plug and gasket. Then check that oil is filled up
from mounting hole for the filler plug.
CAUTION:
Turn the power switch OFF while checking oil level.
• Set a gasket on filler plug and install it on reduction gear and
tighten to the specified torque. Refer to
CAUTION:
• Never reuse gasket.
• If foreign matter, such as gear abrasion powder, is on the
magnet of the filler plug, wipe it free of adherents before
installation.
REDUCTION GEAR OIL : Draining and Refilling
INFOID:0000000010121531
DRAINING
1. Turn the power switch OFF.
2. Remove filler plug.
3. Remove drain plug and drain gear oil.
4. Set a gasket on drain plug and install it to reduction gear and
tighten to the specified torque. Refer to
CAUTION:
• Never reuse gasket.
• If foreign matter, such as gear abrasion powder, is on the
magnet of the drain plug, wipe it free of adherents before
installation.
REFILLING
1. Remove filler plug . Fill with new gear oil until oil level reaches
the specified level near filler plug mounting hole.
2. After refilling oil, check oil level. Set a gasket on filler plug, then
install it to reduction gear. Refer to
.
CAUTION:
• Never reuse gasket.
• If foreign matter, such as gear abrasion powder, is on the magnet of the filler plug, wipe it free of
adherents before installation.

WHEELS : Inspection
INFOID:0000000010121532
APPEARANCE
Check the road wheel for bend, damage, crack or wear.
WHEELS : Wheel Balance Adjustment
INFOID:0000000010121533
BALANCING WHEELS (ADHESIVE WEIGHT TYPE)
Preparation Before Adjustment
Remove inner and outer balance weights from the road wheel. Using releasing agent, remove double-faced
adhesive tape from the road wheel.
CAUTION:
• Be careful not to scratch the road wheel during removal.
• After removing double-faced adhesive tape, wipe clean all traces of releasing agent from the road
wheel.
Wheel Balance Adjustment
CAUTION:
• DO NOT use center hole cone-type clamping machines to hold the wheel assembly during tire
removal/installation or balancing or damage to the wheel paint, cladding or chrome may result. Use
only rim-type or universal lug-type clamping machines to hold the wheel assembly during servicing.
• If a balancer machine has an adhesive weight mode setting, select the adhesive weight mode setting and
skip Step 2 below. If a balancer machine only has the clip-on (rim flange) weight mode setting, follow Step 2
to calculate the correct size adhesive weight.
1. Set road wheel on balancer machine using the center hole as a guide. Start the balancer machine.
2. For balancer machines that only have a clip-on (rim flange) weight mode setting, follow this step to calcu-
late the correct size adhesive weight to use. When inner and outer imbalance values are shown on the
balancer machine indicator, multiply outer imbalance value by 5/3 (1.67) to determine balance weight that
should be used. Select the outer balance weight with a value closest to the calculated value above and
install in to the designated outer position of or at the designated angle in relation to the road wheel.
a. Indicated imbalance value
× 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz)
× 5/3 (1.67) = 38.33 g (1.35 oz) ⇒ 40 g (1.41 oz)
balance weight (closer to calculated balance weight value)
NOTE:
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4
⇒ 35 g (1.23 oz)
37.5
⇒ 40 g (1.41 oz)

3. Install balance weight in the position shown.
CAUTION:
• Do not install the inner balance weight before installing
the outer balance weight.
• Before installing the balance weight, be sure to clean the
mating surface of the road wheel.
• When installing balance weight (1) to road wheel, set it into the
grooved area (A) on the inner wall of the road wheel as shown
so that the balance weight center (B) is aligned with the bal-
ancer machine indication position (angle) (C).
CAUTION:
• Always use Genuine NISSAN adhesive balance weights.
• Balance weights are non-reusable; always replace with
new ones.
• Do not install more than three sheets of balance
weights.
4. If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other as shown.
CAUTION:
Do not install one balance weight sheet on top of another.
5. Start balancer machine again.
6. Install balance weight on inner side of road wheel in the bal-
ancer machine indication position (angle).
CAUTION:
Do not install more than two balance weights.
7. Start balancer machine. Make sure that inner and outer residual
imbalance values are 5 g (0.17 oz) each or below.
8. If either residual imbalance value exceeds 5 g (0.17 oz), repeat installation procedures.
WHEELS : Tire Rotation
INFOID:0000000010121534
• Follow the maintenance schedule for tire rotation service intervals.
Refer to
MA-7, "FOR USA AND CANADA : Explanation of General
(For United States and Canada) or
(For Mexico).
• When installing the wheel, tighten wheel nuts to the specified
.
CAUTION:
• When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
• Be careful not to tighten wheel nut at torque exceeding the
criteria.
• Use NISSAN genuine wheel nut.
• Perform the ID registration, after tire rotation. Refer to
